Question

1. is this process reversible by simple physical means? why or why not?

part 7: challenge section
balance and classify the following reactions:

1. na + cl₂ → nacl

type:
balanced:

1. h₂o₂ → h₂o + o₂

type:
balanced:

1. c₂h₂ + o₂ → co₂ + h₂o

type:
balanced:

Explanation:

Step1: Balance the first reaction

$2Na + Cl_2
ightarrow 2NaCl$. This is a synthesis reaction as two substances combine to form one product.

Step2: Balance the second reaction

$2H_2O_2
ightarrow 2H_2O + O_2$. This is a decomposition reaction as one substance breaks down into two products.

Step3: Balance the third reaction

$2C_2H_2 + 5O_2
ightarrow 4CO_2+2H_2O$. This is a combustion reaction as a hydrocarbon reacts with oxygen to produce carbon - dioxide and water.

Answer:

1. Type: Synthesis; Balanced: $2Na + Cl_2

ightarrow 2NaCl$

1. Type: Decomposition; Balanced: $2H_2O_2

ightarrow 2H_2O + O_2$

1. Type: Combustion; Balanced: $2C_2H_2 + 5O_2

ightarrow 4CO_2+2H_2O$
